[0028] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] The embodiment of the present application provides a window air conditioner to solve the technical problem of poor heat dissipation effect of the electric control box of the window air conditioner in the prior art.

[0031] In the embodiments of the present application, Figure 1-Figure 4 As shown, the window air conditioner includes a chassis 10, an electric control box 20 and a refrigerant pipe 30. A water storage tank 11 is provided on the chassis 10; the electric control box 20 includes a box body 21, a heating element 22 and a heat sink 23 arranged in the box body 21, and the heat sink 23 is connected to the heating element 22; the refrigerant pipe 30 includes a first pipe section 31, a second pipe section 32 and a third pipe section 33, the first pipe section 31 and the second pipe section 32 are arranged in the water storage tank 11 at intervals, the two ends of the third pipe section 33 are connected to the first pipe section 31 and the second pipe section 32 respectively, and the third pipe section 33 is at least partially installed in the box body 21 and fits the heat sink 23.

[0032] It should be noted that when the window air conditioner is running, a large amount of heat will be generated inside the electric control box 20. If the heat dissipation of the components in the electric control box 20 is not timely, the normal operation of the window air conditioner may be affected. At present, most of the existing technologies install heat sinks on the electric control box, and use the negative pressure formed by the outdoor fan blades to take away the heat of the heat sink to achieve the heat dissipation effect. However, when the outdoor ambient temperature is high, the heat dissipation speed of heat sinks is slow, the heat dissipation efficiency is low, and the heat dissipation effect is poor, which cannot guarantee the normal operation of the window air conditioner.

[0033] To this end, the window air conditioner provided in the present application is achieved by fitting the third pipe segment 33 of the refrigerant pipe 30 with the heat sink 23, and the heat sink 23 is connected to the heating element 22. The third pipe segment 33 can be indirectly connected to the heating element 22 and realize heat exchange, thereby cooling the heating element 22. At the same time, the first pipe segment 31 and the second pipe segment 32 are arranged in the water tank 11 at intervals, which can effectively avoid mutual heat transfer between the first pipe segment 31 and the second pipe segment 32. The condensed water in the water tank 11 can further reduce the temperature of the refrigerant in the first pipe segment 31 and the second pipe segment 32, so that the temperature of the refrigerant flowing through the third pipe segment 33 is lower, thereby further improving the heat dissipation efficiency of the electric control box 20, and the heat dissipation effect is better, which is conducive to ensuring the normal operation of the window air conditioner.

[0034] Specifically, the refrigerant pipe 30 is connected to the refrigeration system of the window machine to form a loop. When the refrigerant of the refrigeration system flows through the third pipe section 33, the refrigerant absorbs the heat transferred from the heating element 22 to the heat sink 23, thereby reducing the temperature of the electric control box 20. Moreover, as the refrigerant continuously circulates in the refrigeration system, the refrigerant can continuously absorb the heat of the electric control box 20, so that the heating element 22 in the electric control box 20 is kept at a relatively low temperature for a long time, and the heat dissipation effect of the electric control box 20 is good and the heat dissipation efficiency is high.

[0035] See also Figure 2 It can be understood that the chassis 10 generally includes an indoor side and an outdoor side, the indoor side is placed in the indoor space, the outdoor side is placed in the outdoor space, and the water storage tank 11 is arranged on the outdoor side of the chassis 10. An evaporator is arranged on the indoor side of the chassis 10. When the window machine is in cooling operation, a large amount of condensed water will be generated during the heat exchange between the evaporator and the indoor air. The condensed water drips onto the indoor side of the chassis 10 and then flows into the water receiving tank. The temperature of the condensed water is relatively low, usually only a dozen degrees. Therefore, by placing both the first pipe section 31 and the second pipe section 32 in the water receiving tank, the condensed water is used to further cool the refrigerant in the first pipe section 31 and the second pipe section 32, so that the heat dissipation effect of the electric control box 20 can be improved, so that the heating element 22 in the electric control box 20 can be kept at a relatively low temperature for a long time. At the same time, since the electric control box 20 controls the operation of the window machine, the improvement of the heat dissipation efficiency of the electric control box 20 will also improve the operation of the window machine, thereby improving the cooling efficiency of the window machine.

[0036] More specifically, one end of the first pipe section 31 away from the third pipe section 33 is connected to the condenser, and one end of the second pipe section 32 away from the third pipe section 33 is connected to the evaporator. When the window mechanism is in cooling operation, the gaseous refrigerant discharged from the compressor is processed by the condenser to form a liquid refrigerant, and the liquid refrigerant enters the first pipe section 31 after being processed by the one-way throttle valve, and then the refrigerant flows in the third pipe section 33 and the second pipe section 32 in turn, and finally flows to the evaporator. Since the refrigerant in the second pipe section 32 absorbs the heat generated by the heating element 22, the temperature of the refrigerant in the second pipe section 32 is higher than the temperature of the refrigerant in the first pipe section 31. Therefore, in this embodiment, by arranging the first pipe section 31 and the second pipe section 32 in the water storage tank 11 at intervals, it is possible to effectively avoid the second pipe section 32 from transferring heat to the first pipe section 31, thereby ensuring the heat dissipation efficiency of the electric control box 20.

[0037] In addition, in order to improve the heat exchange efficiency between the refrigerant pipe 30 and the heat sink 23, the heat sink 23 can be made of metal material, for example, the heat sink 23 is an aluminum plate; similarly, the refrigerant pipe 30 can also be made of a copper tube or an aluminum tube.

[0038] Optionally, in one embodiment, see Figure 2 , Figure 5 and Figure 6 The chassis 10 has a first end 17 and a second end 18 that are relatively arranged, and the height of the second end 18 is higher than the height of the first end 17 so that the chassis 10 is inclined in the first direction; the first pipe section 31 and the second pipe section 32 both extend in the second direction, the first direction and the second direction are not parallel to each other, and the first pipe section 31 and the second pipe section 32 are both arranged close to the first end 17.

[0039] It can be understood that the first end 17 is placed on the outdoor side and the second end 18 is placed on the indoor side. In order to facilitate the drainage of the chassis 10, the chassis 10 has a certain inclination angle with the horizontal plane during installation. The inclination angle can be 5°, so that the condensed water generated on the indoor side of the chassis 10 can flow toward the outdoor side under the action of gravity. Figure 6 As shown, the condensed water is mostly accumulated on the outdoor side of the chassis 10 away from the indoor side, that is, the condensed water is mostly accumulated at the first end 17 of the chassis 10. Therefore, by arranging the first pipe section 31 and the second pipe section 32 close to the first end 17, it is beneficial to ensure that the first pipe section 31 and the second pipe section 32 are both immersed in the condensed water, so that the refrigerant in the refrigerant pipe 30 is always at a lower temperature, thereby ensuring the heat dissipation effect of the electrical control box 20.

[0040] Exemplarily, the first direction and the second direction are perpendicular to each other, which is helpful to ensure that the first pipe section 31 and the second pipe section 32 can be mostly immersed in the condensed water, further ensuring the heat dissipation effect of the electric control box 20.

[0041] For further information, see Figure 5-Figure 7 , a plurality of convex bumps 12 are arranged at intervals on the chassis 10, the first pipe section 31 and the second pipe section 32 are respectively against the two sides of the convex bumps 12, and the thickness of the plurality of convex bumps 12 decreases in sequence along the second direction. In this embodiment, by arranging a plurality of convex bumps 12 at intervals between the first pipe section 31 and the second pipe section 32, it is ensured that the first pipe section 31 and the second pipe section 32 do not fit together, the contact risk is reduced, and the heat transfer between the first pipe section 31 and the second pipe section 32 is avoided.

[0042] See also Figure 6 Since the chassis 10 is tilted in the first direction, the first pipe segment 31 can be completely immersed in the condensed water under normal circumstances, while the second pipe segment 32 is only partially immersed in the condensed water. Therefore, in this embodiment, the thickness of the convex hump 12 is gradually reduced in the second direction, thereby reducing the distance between the first pipe segment 31 and the second pipe segment 32. When the first pipe segment 31 and the second pipe segment 32 do not transfer heat to each other, the second pipe segment 32 can be arranged as close to the first pipe segment 31 as possible, which is beneficial to ensure that the second pipe segment 32 can be immersed in the condensed water to a greater extent, thereby reducing the temperature of the refrigerant in the second pipe segment 32.

[0043] In addition, by reducing the distance between the first pipe section 31 and the second pipe section 32 in the first direction, it is convenient to connect the first pipe section 31 to the condenser and the second pipe section 32 to the evaporator, which is beneficial to ensure the compactness of the internal structure of the window machine and facilitate assembly.

[0044] Optionally, in one embodiment, see Figure 5 and Figure 8A stopper 13 is further provided on the chassis 10 . The stopper 13 has a first pipe groove 131 and a second pipe groove 132 which are arranged at intervals. The first pipe section 31 is engaged in the first pipe groove 131 , and the second pipe section 32 is engaged in the second pipe groove 132 .

[0045] Specifically, the first pipe section 31 and the second pipe section 32 are both arranged horizontally, that is, the first pipe section 31 and the second pipe section 32 are both lying flat in the water receiving trough, the cross-section of the limiting member 13 is roughly "W"-shaped, the limiting member 13 can be made of elastic material, the first pipe groove 131 is adapted to the shape of the first pipe section 31, for example, in this embodiment, an arc-shaped first pipe groove 131 can be arranged on the limiting member 13, and preferably a major arc, that is, an arc larger than a semicircle, because the limiting member 13 is elastic, by directly inserting the first pipe section 31 into the first pipe groove 131, the first pipe section 31 can be limited in the horizontal direction, so as to prevent the vibration generated by the operation of the window machine from causing the first pipe section 31 to move in the horizontal direction, thereby ensuring the reliability of the pipeline assembly.

[0046] Similarly, the second pipe groove 132 can also be set to an arc shape. By directly inserting the second pipe section 32 into the second pipe groove 132, the second pipe section 32 can be limited in the horizontal direction to prevent the vibration generated by the operation of the window machine from causing the second pipe section 32 to move in the horizontal direction, thereby ensuring the reliability of the pipeline assembly. In addition, since the first pipe groove 131 and the second pipe groove 132 are arranged at intervals, it is beneficial to ensure the distance between the first pipe section 31 and the second pipe section 32, and avoid heat transfer between the first pipe section 31 and the second pipe section 32. In order to further improve the reliability of the pipeline assembly, the first pipe section 31 and the second pipe section 32 can also be limited by setting a plurality of limit members 13.

[0047] Optionally, in one embodiment, see Figure 5 A first fixing column 14 is provided on the side of the first pipe section 31 facing away from the second pipe section 32, and the first fixing column 14 abuts against the first pipe section 31; and / or a second fixing column 15 is provided on the side of the second pipe section 32 facing away from the first pipe section 31, and the second fixing column 15 abuts against the second pipe section 32.

[0048] Specifically, the first fixing column 14 and the second fixing column 15 are both fixedly connected to the chassis 10, for example, the first fixing column 14 and the second fixing column 15 can be directly welded to the chassis 10. It can be understood that, in order to facilitate assembly and ensure that the first pipe section 31 and the second pipe section 32 can be immersed in condensed water, the first pipe section 31 and the second pipe section 32 are usually arranged in a multi-folded manner. Therefore, in this embodiment, by arranging the first fixing column 14 and the second fixing column 15, the first fixing column 14 can limit the side of the first pipe section 31 that is away from the second pipe section 32 to ensure that the first pipe section 31 can be immersed in condensed water; the second fixing column 15 can limit the side of the second pipe section 32 that is away from the first pipe section 31 to ensure that the second pipe section 32 can be immersed in condensed water, which is conducive to ensuring the heat dissipation effect of the electric control box 20 and improving the heat dissipation performance of the electric control box 20.

[0049] Optionally, in one embodiment, see Figure 5 and Fig. 9 A plurality of pipe clamps 16 are provided on the chassis 10, and the first pipe section 31 and the second pipe section 32 are fixed in the water storage tank 11 by the pipe clamps 16. The pipe clamps 16 are mainly used to fix the first pipe section 31 and the second pipe section 32 in the vertical direction to prevent the first pipe section 31 and the second pipe section 32 from loosening, and have high reliability.

[0050] For details, please refer to Fig. 9 The pipe clamp 16 includes a pressing plate 161 and screws for fixing the pressing plate 161 on the chassis 10. A plurality of ribs 162 are arranged at intervals on one side of the pressing plate 161 facing the chassis 10. A pipe opening 163 for the first pipe section 31 or the second pipe section 32 to pass through is formed between any two adjacent ribs 162. A first screw hole is provided on the pressing plate 161, and a second screw hole corresponding to the first screw hole is provided on the chassis 10. The pressing plate 161 can be fixed on the chassis 10 by passing the screws through the first screw hole and the second screw hole in sequence. In this embodiment, two pipe openings 163 are formed on the pressing plate 161. The two pipe openings 163 are used to pass through the first pipe section 31 and the second pipe section 32 respectively, so as to limit the first pipe section 31 and the second pipe section 32. The ribs 162 are provided to ensure the distance between the first pipe section 31 and the second pipe section 32, so as to prevent the first pipe section 31 and the second pipe section 32 from contacting and transferring heat.

[0051] In some embodiments, the pipe clamp 16 cooperates with the first fixing column 14 to achieve fixation, that is, the first fixing column 14 is fixed to the chassis 10 by welding, and a first screw hole is set on the pressure plate 161, and a second screw hole is set on the first fixing column 14. The pressure plate 161 can be indirectly fixed to the chassis 10 by passing the screws through the first screw hole and the second screw hole in sequence. This fixing method is more stable and easy to operate.

[0052] Optionally, in one embodiment, see Figure 3 and Figure 4 The heat sink 23 includes a first heat sink 231 and a second heat sink 232 that are connected to each other. An avoidance groove 233 is provided between the first heat sink 231 and the second heat sink 232 , and the third pipe section 33 is installed in the avoidance groove 233 .

[0053] It can be understood that when the window air conditioner is a variable frequency air conditioner, the heat generated by the electric control box 20 of the variable frequency window air conditioner during operation is greater than the heat generated by the electric control box 20 of the fixed frequency window air conditioner. Therefore, in this embodiment, two heat sinks 23 are arranged, and the third pipe section 33 is placed in the avoidance groove 233 between the first heat sink 231 and the second heat sink 232, so that the heat exchange effect between the refrigerant and the heating element 22 is better, thereby further improving the heat dissipation efficiency and heat dissipation effect of the variable frequency window air conditioner, and ensuring the normal operation of the variable frequency window air conditioner.

[0054] For further information, see Figure 2-Figure 4 The third pipe section 33 includes a U-tube 331 , a first straight tube 332 and a second straight tube 333 , and both ends of the U-tube 331 are respectively connected to the first straight tube 332 and the second straight tube 333 , and the first straight tube 332 and the second straight tube 333 are placed in the avoidance groove 233 .

[0055] The first heat sink 231 and the second heat sink 232 are generally rectangular plate structures. The side of the first heat sink 231 facing the second heat sink 232 is planar, and two avoidance grooves 233 with semicircular cross-sections are provided on the side of the first heat sink 231 facing the second heat sink 232; similarly, the side of the second heat sink 232 facing the first heat sink 231 is planar, and two avoidance grooves 233 with semicircular cross-sections are provided on the side of the second heat sink 232 facing the first heat sink 231.

[0056] During installation, the first straight tube 332 and the second straight tube 333 are first fixed in the two semicircular avoidance grooves 233 of the first heat sink 231, and then the second heat sink 232 with the avoidance groove 233 is covered on the first heat sink 231 to achieve assembly. Since the first straight tube 332 and the second straight tube 333 of the third pipe section 33 can exchange heat with the heat sink 23, the heat exchange area is increased, so that the heat dissipation effect of the electric control box 20 is better.

[0057] For further information, see Figure 3, a buckle 24 is provided in the box body 21, and the U tube 331 is engaged with the buckle 24. When the first straight tube 332 and the second straight tube 333 are respectively fixed in the two semicircular avoidance grooves 233 of the first heat sink 231, in order to prevent the third pipe section 33 from sliding relative to the first heat sink 231, in this embodiment, the buckle 24 is provided in the electric control box 20 to fix the U tube 331, so as to prevent the first straight tube 332 or the second straight tube 333 from falling off from the avoidance groove 233 during installation. In addition, in order to further ensure the stability of the third pipe section 33 during installation, the first straight tube 332 and the second straight tube 333 can also be fixed by the buckle 24.
